Pokerstars Froze my account

[luckychancer]

Well my UK credit card gets used regularly, so that's no reason.
However going back to the top....

Let's pretend I've never had a Pokerstars account and never had to provide all this info in order to make a deposit on a poker site. I used the same card to fund my Fulltilt account in the same manner with no problem whatsoever.

Shouldn't they let me know in advance all this stuff will be required?
Isn't it underhanded to get the cash then hold it hostage?
